IMPROVEMENT IN MACHINES FOR ASSORTING PINS.

Specification forming part of Letters Patent N o. 166,] 53, dated July27,1875; application filed June 26, 1875.

ters and figures of reference marked thereon..

Figure 1 of the drawings is a representation of a longitudinal verticalsection of my pin-assorter, and Fig. 2 is a plan view of the same. Fig.3 is an end View.

This invention has relation to improvements in machines which aredesigned to'separate the straight from the bent or crooked pins; and thenature of the invention consists in the combination, with an inclinedchute for receiving the pins as they fall from the feed-apron, of alongitudinally-grooved separating-roller at the lower end of the saidchute, in the grooves of which the pins will be received during itsrotation, and will be delivered into a suitable receptacle therefor. Italsoconsists in combining, with an inclined chute and a longitudinallygrooved roller, a rotating brush, mounted in bearings above the saidroller, with its free ends touching its periphery, whereby crooked pinslying in or over the grooves will be swept back up the inclined surfaceof the chute against a shelf fixed diagonally across the same, and willbe delivered at the side of the machine, the straight pins beingdelivered at its end. It moreover consists in the novel construction,arrangement, and co-operation of the various devices used, as will behereinafter more fully explained and claimed.

In the annexed drawings, A designates the uprights, and B the base, ofthe rectangular frame of my improved device for separating straight andcrooked pins. This frame affords bearings at its upper ends for tworollers, a a, over which is passed an endless apron, C, which may be ina horizontal position, or at an inclination thereto, as I may elect. Drepresents an inclined chute, consisting of a floor, a ceiling, andinclosing side walls, which extends from roller a/at one end of theframean end and a purpose which will hereafter] fully appear. Frepresents a brush-roller, which is provided with a number of spaced andpreferably alternating Whisks, d, and whichis arranged above roller E,with its hearings in uprights A, as shown.

Motion is communicated from the shaft of roller E to feed-apron by meansof an endless belt, G, passing over pulleys e 6, respectively,

on the said shaft, and on the corresponding end of roller a, and also tobrush-roller F, by

means of an endless belt, H, passing over a pulley-wheel, f, on theother end of the said shaft, and a pulley, g, on the corresponding endof brush-roller E 5 consequently, when the said roller is caused torotate by a suitable motor, the feed-apron and the brush-roller will besimultaneously actuated, the direction of the rotation of the saidbrush-roller being opposite to that of the grooved roller. It beingdesirable that the former should rotate with great speed, while themovements of the latter may be slower, pulley y will be necessarily ofsmall size in comparison to pulley f on the end of the shaft of rollerE.

The operation of my improved machine is as follows: The pins fallingfrom the machine on which they are made upon feedapron C will bedelivered into the open upper end of chute D, and will be conducted togrooved roller E. The perfectly straight pins will be received andcompletely buried in the grooves c of the latter, while the crooked orslightlybent ones will be partly in and partly out of the said grooves,so that they will be either swept out of the same by the touch of theWhisks or by the blast of air caused by their revolution, up and backagainst a shelf, h, diagonally arranged across the upper surface of thechute, striking against which they will be thrown clear of and to oneside of the machine.

The straight pins and those but slightly bentl from crooked pins, the1011 gitudinallygrooved that is to say, so slightly bent as to becapable of lying in the grooves of the roller E-- will be carried overthe latter, and the straight pins will roll off the inclined lower edgesof the grooves the moment they are inclined by the rotation of the saidroller from the horizontal plane, falling outside of a receptacle orbox, H, arranged under the roller with its outer wall extending upwardin a curve very nearly in contact with the said roller. Theslightly-bent pins will be held in the grooves, owing to theircurvature, and will be carried by the revolution of roller E intoreceptacle or box H.

By this means pins will be separated into three classesnamely, theperfectly straight, the slightly bent, and the very crooked-by one andthe same machine, and with great rapidity.

What I claim as new, and desire to secure by Letters Patent, is

1. In a machine for separating straight roller E, in combination withtheinclined chute D and feed-apron (J, substantially as specified.-

2. The brush-roller F, in combination with the longitudinally groovedcylinder E and chute D, substantially as specified.

3. The shelf h, in combination with chute D, grooved cylinder E, andbrush-roller F, substantially as specified.

4. The roller E, having beveled grooves 0, in combination with thereceptacle or box H, substantially as specified.

5. The apron O, chute D, shelf h, grooved roller E, brush-roller F, andreceptacle, arranged, combined, and cooperating substantially asdescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN D. SHELTON.
